Tliis is, as far as I have seen, an alga sparlngly disper- 

 sed along the coast of East-Finmarken. . I have foiind it only 

 at two places, growing in rocb-pools " in the lower part of 

 the litoral zone, and in the sublitoral zone on a depth of 



+ 



4 — 6 fathoms.

Litoral (and sublitoral?), appearing on open coast as well
